Everything came together before the final climb of Mount Lofty. An alert Lemmen was able to counter his rivals’ attacks in the final kilometres. In the end, the Dutchman was beaten by stage and overall winner Williams, Isaac Del Toro and Jhonatan Narváez. His fourth place saw Lemmen move up to fifth in the final standings.

"Our goal was to defend Bart's position in the general classification, and we did that", sports director Addy Engels said. "We knew that the stage would be decided on the final climb of Mount Lofty. The focus was right, although, unfortunately, both Milan (Vader) and Johannes (Staune-Mittet) crashed in the final stages. Despite this, his teammates gave Bart the perfect support to fight for the day's victory. Fourth place on this tough finish is a great result."

Lemmen, in his first few months with Team Visma | Lease a Bike, finished his first stage race at WorldTour level in the top five. "This is just an outstanding performance", Engels added. "The riders that were here were of a very high level. Both today and yesterday, Bart managed to keep some big names behind him on challenging courses. What he has shown this week as a newcomer has been great."
